Abstract
Abstract An arrangement for alignedly coupling two coated light-conductive fibers includes three clamping rods which are supported in a support sleeve by a deflectable element and two actuating elements are introduced into the sleeve from two opposite ends thereof and inwardly deflect the deflectable element to press the clamping rods into a clamping engagement with the stripped portions of light-conductive fibers located therebetween. Each of the actuating elements has a longitudinal channel therein through which the respective light-conductive fibers to be coupled pass, each channel including three sections one of which receives the coated cable, another one of which accepts the stripped end portion of the cable, and a next one of which accommodates ends of the clamping rods. Because of its configuration, the channel prealigns the fiber with a passage defined by the clamping rods during the introduction of the fiber into the arrangement. The support sleeve may consist of two components one of which is configurated as a receptacle for partially receiving the other component in a plug-in fashion to facilitate assembly and disassembly of the components. In the latter event, each of the fibers to be coupled is attached to one of the components of the support sleeve even when the components are disassembled from one another.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
239 words
An arrangement for alignedly coupling two coated light-conductive fibers, comprising a support sleeve including two assemblable components, one of said components having a tubular region which bounds a receiving recess and another region axially adjacent said tubular region, the other of said components having at least an end region which is so configurated as to be fittingly received in said receiving recess upon assembly; three clamping rods; means for so mounting said clamping rods in said other component of said support sleeve as to extend parallel to each other and define with one another a passage for receiving respective stripped end portions of the light-conductive fibers, including at least one deflectable portion; means for inwardly deflecting said deflectable portion to press said clamping rods into a clamping contact with the end portions of the light-conductive fibers, including an actuating portion of said one component of said support sleeve; and means for affixing a respective one of said light-conductive fibers to said one component of said support sleeve, including three additional clamping rods which are so mounted in said other region of said one component of said support sleeve as to extend parallel to each other and define with one another an additional passage for partially receiving the respective light-conductive fiber, and means for inwardly pressing said additional clamping rods into a clamping engagement with that portion of the respective light-conductive fiber which is received between said additional clamping rods.
Claim 2
Dependent Claim
239 words
An arrangement for alignedly coupling two coated light-conductive fibers, comprising a support sleeve including two assemblable components, one of said components having a tubular region which bounds a receiving recess and another region axially adjacent said tubular region, the other of said components having at least an end region which is so configurated as to be fittingly received in said receiving recess upon assembly; three clamping rods; means for so mounting said clamping rods in said other component of said support sleeve as to extend parallel to each other and define with one another a passage for receiving respective stripped end portions of the light-conductive fibers, including at least one deflectable portion; means for inwardly deflecting said deflectable portion to press said clamping rods into a clamping contact with the end portions of the light-conductive fibers, including an actuating portion of said one component of said support sleeve; and means for affixing a respective one of said light-conductive fibers to said one component of said support sleeve, including three additional clamping rods which are so mounted in said other region of said one component of said support sleeve as to extend parallel to each other and define with one another an additional passage for partially receiving the respective light-conductive fiber, and means for inwardly pressing said additional clamping rods into a clamping engagement with that portion of the respective light-conductive fiber which is received between said additional clamping rods.
Claim 3
Dependent Claim
64 words
An arrangement as defined in claim 1, wherein said pressing means includes an actuating screw threaded into said other region of said one component of said support sleeve and additional mounting means having at least one deflectable portion which is interposed between said actuating screw and said one component and is inwardly deflected against said additional clamping rods upon tightening of said actuating screw.
Claim 4
Dependent Claim
99 words
An arrangement as defined in claim 2, wherein said actuating screw has a channel therein which partially accommodates the respective light-conductive fiber; and further comprising means for de-tensioning at least that portion of the respective light-conductive fiber which is accommodated in said channel, including a protective socket surrounding said actuating screw and having one end connected to, and another end remote from, said one component of said support sleeve, and means for engaging the respective light-conductive fiber at said other end of said protective socket and for transmitting tensile forces from the respective light-conductive fiber to said protective socket.
Claim 5
Dependent Claim
116 words
An arrangement as defined in claim 1, wherein said one component of said support sleeve bounds an elongated channel through which the respective fiber passes in a predetermined direction during the introduction thereof into the arrangement, said channel including, as considered in said direction, a first channel zone which partially accommodates said actuating screw and fully receives said mounting means, a second channel zone having a cross section large enough to partially receive said additional clamping rods, a third channel zone having a cross section coordinated to that of the respective stripped light-conductive fiber, and a fourth channel zone having a cross section large enough to partially receive said clamping rods upon assembly of said components.
